Fellow Backstreet Boys member Howie Dorough told CBSNews.com Monday he was still recovering from the wedding weekend. "It was unbelievable and crazy," he said. "I wouldn't expect anything different from A.J. Very gothic, very out there. It was lots of fun. All the guys were there. We partied. We danced our butts off. It was great seeing another one of our guys go down that aisle."

Other guests included Kathy Griffin, Joey McIntyre of the New Kids on the Block, former Backsteet Boys member Kevin Richardson, along with current members Brian Littrell and Nick Carter. Celebrity photographer Tyler Shields officiated the ceremony, according to Us Weekly.
